I got a 95 RT10 delivered on Thursday.
It has 4 codes.
12 - normal battery disconnect
31 - evap
42- ASD
43 - multiple/single misfire
42 and 43 combined with my reverse lockout challenge made me think the O2 sensor wiring had melted, grounding the circuit and killing the reverse lockout and O2 sensor that I hear share a circuit. That combined with a burning plastic smell made me think my diagnosis was likely to be right.
So I pulled the side sill and came to find a replaced cat and Borla muffler and no down stream O2 sensor.
Does the 95 have just one O2 sensor per bank. I watched a Youtube video of a guy pulling his stock exhaust off of a 93 and I didn't see a downstream O2 sensor on it. I'm trying to decide between to possibilities: previous owner deleted the donwnstream O2 sensor or there never was one.
Do you think the problem is with the upstream O2 then?
